“It was by accident! I didn’t know what they were,” the “Jeopardy” host told the Daily Beast in an interview published Wednesday. “I had just arrived in California and went to a friend’s house for dinner, and there were brownies.”

The self-proclaimed “chocoholic” said he didn’t realize they were hash brownies.

“And … whoa. That threw me for a loop. I took down about a half-dozen,” said Trebek, 77. “The dinner party was on a Friday, and I was not able to leave that house until Sunday afternoon. I spent the next day and a half in bed.”

He added, “It was not a good trip, and I have not done any of that stuff since!”

The Canadian native began hosting “Jeopardy” in 1984 and has a contract with the show through 2020.
